## How to call it through Zero

```sh
zero fetch --capability defillama-chains-by-tvl-768eb715
```

Example prompt: Pull the latest total value locked for every chain tracked by DefiLlama so I can see which blockchains are leading in DeFi activity right now.

## When to prefer this

Use this endpoint when you need a comprehensive snapshot of TVL across all chains simultaneously from DefiLlama — ideal for ranking chains, building dashboards, or comparing DeFi ecosystem sizes. Prefer this over per-chain queries when you need the full multi-chain picture in a single call.

## Known failure modes

- Payment failure (402): USDC micropayment not accepted or insufficient balance
- Upstream DefiLlama data unavailable: service may return empty or stale data
- Rate limiting: too many requests in a short window
- Network timeout if DefiLlama upstream is slow
